BACKGROUND ART Conventionally, there has been known a plant cultivation apparatus for cultivating plants such as vegetables such as lettuce and fruits by hydroponics (for example, Patent Document 1). The plant cultivation apparatus described in Patent Document 1 is said to be able to be installed in limited spaces such as underground tunnels and underground shopping malls, and to cultivate plants such as vegetables and fruits without using pesticides without pests.

JP 2018-023336 A

By the way, when leaf vegetables grown by hydroponics are harvested, the stems of the leaf vegetables are cut and harvested parts such as leaves are harvested as in the conventional method. When harvesting leaf vegetables, conventionally, the vegetables have been manually cut and harvested one by one by human eyes and senses. Therefore, there is a problem that it takes a long time to harvest, and a large amount of harvest requires a lot of manpower, resulting in poor harvesting efficiency.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a harvesting device capable of harvesting more efficiently than conventional ones.

One aspect of the present invention for solving the above problems is a harvesting device for harvesting a harvested portion of the harvested product from a cultivation tray in which the harvested product is cultivated, the cutting device cutting a part of the harvested product. The harvesting device has a section and a lifting section, and the lifting section lifts the harvested material cut by the cutting section and sends the harvested section to an external conveying section that conveys the harvested section to the outside.

According to this aspect, since the harvested material after cutting a part of the harvested material is lifted by the lifting section and the harvested portion is sent to the external transportation section, automatic harvesting and transportation to the outside are possible.

In a preferred aspect, the lifting part is plate-like and has a notch, and the notch engages and lifts the crop cut by the cutting part.

According to this aspect, the cut harvested material is lifted by the notch of the lifting part. Therefore, for example, by forming a notch portion that matches the outer shape of the harvested portion, the harvested portion is less likely to be damaged when lifted, and a good-looking harvested portion can be harvested.

In a preferred aspect, the lifting portion has a shaft portion and a rotating portion that rotates around the shaft portion, and lifts the harvested material cut by the cutting portion as the rotating portion rotates. That is.

According to this aspect, since the harvested material cut by the cutting section is lifted as the rotation section rotates, the mechanism for lifting the harvested material can be simplified.

A preferred aspect is that the lifting section sends the harvested section upside down to the external conveying section.

According to this aspect, since the harvested parts are sent to the external conveying part in an upside-down posture, it is easy to perform pruning work and packing work on the harvested parts conveyed by the external conveying part.

A preferred aspect has a tray conveying section that conveys the cultivation tray toward the cutting section, the cutting section has a blade section, and the blade section conveys the cultivation tray in the tray conveying section. by contacting and cutting a part of said harvest.

According to this aspect, the blade portion comes into contact with the harvested material as the tray conveying section carries out the conveying operation, and a part of the harvested material can be automatically cut, so that more efficient harvesting is possible.

A preferred aspect has a tray transport section that transports the cultivation tray toward the cutting section in the first transport direction, the lifting section has a curved upstream end in the first transport direction, and the The cultivation tray is conveyed to the cutting section while the upper surface is in contact with or close to the curved surface of the lifting section.

"Proximity" here means that the shortest distance is within 1 cm.

According to this aspect, the cultivation tray is conveyed to the cutting section while the upper surface of the cultivation tray is in contact with or close to the curved surface of the lifting section. You can prevent it from getting stuck in the part.

A more preferred aspect is that the cultivation tray is partially cut by the cutting section while the upper surface of the cultivation tray is in contact with or close to the curved surface of the lifting section.

According to this aspect, even if the cultivation tray tries to float up as part of the harvested material is cut at the cutting section, the upper surface is pressed down by the curved surface, so that the cultivation tray can be prevented from floating upward. .

In a preferred aspect, the cultivation tray has a tray body and a holding part, the tray body has a mounting hole, and the holding part surrounds a part of the harvest. and the harvested product is attached to the tray main body portion by inserting a part or the whole of the harvested product into the attaching hole.

It is capable of sucking the residue on the cultivation tray of the crop cut by the cutting section sent to the section, and is movable in the direction intersecting the first conveying direction.

The term "residues of the harvested material" as used herein refers to wastes unnecessary for harvesting that have fallen from the harvested material to the cultivation tray or the like when the harvested material is lifted by the lifting section or cut by the cutting section.

According to this aspect, since the suction unit can move in the direction that intersects the first conveying direction of the cultivation tray of the tray conveying unit, cleaning on the cultivation tray is easy, and the presence of residue of the harvested product. It is possible to prevent malfunction due to

In a preferred aspect, said cultivation tray is grown with at least two crops spaced apart and has at least two cuts, said two cuts each being part of said two crops. can be cut substantially simultaneously, and the lifting section can simultaneously lift the two crops cut by the two cutting sections and send them to the external conveying section.

Here, "substantially simultaneously" means that the time difference between the cutting of the harvested material by one cutting section and the cutting of the harvested material by the other cutting section is within 1 second.

According to this aspect, harvested parts can be harvested simultaneously from a plurality of crops.

A preferred aspect includes a tray conveying section that conveys the cultivation tray toward the cutting section in a first conveying direction, and the cultivation tray allows at least two crops to be cultivated with a gap in the first conveying direction. and the tray conveying section moves the cultivation tray in the first conveying direction after the cutting section cuts a portion of the harvested material on the downstream side in the first conveying direction among the two harvested materials. is conveying in the opposite direction.

According to this aspect, since the cutting unit retracts the cultivation tray after cutting a part of the harvested material on the downstream side in the first conveying direction, the harvested material on the upstream side in the first conveying direction rather than the harvested crops It is possible to prevent the lifting part from interfering with the
